Gartner's "Collaborative Product Commerce Magic Quadrant for 4Q01"
evaluates and positions 20 vendors in the fast-growing CPC market.
Based on Gartner's analysis, MatrixOne is the highest ranked vendor
in ability to execute CPC solutions in the Enterprise Leaders section
of the quadrant. Gartner cited a number of factors for MatrixOne's
positioning, including demonstrated ability to realize a CPC vision
through software, positive customer feedback and strong financial
performance throughout 2001. Gartner also reported that MatrixOne
customers are pleased with the company's eMatrix software for ease of
implementation, flexible data modeling, Web support and strong
initiatives toward interoperability with heterogeneous engineering
data.

The report places the major CPC vendors into one of four quadrants
- Enterprise Leader, Challenger, Visionary, or Niche Player. It
affirms Gartner's belief that opportunities to collaborate within
individual value chain activities are increasing. Enterprise Leaders
were selected based on customer feedback, profit, total revenue,
revenue growth, strength of management team, marketing capabilities,
breadth of industries served, depth of penetration in those
industries, cash flow, and balance sheet.

MatrixOne has been a pioneer in the field of product
collaboration, and has over 575 customers using its solutions. Its
extensive client base is particularly strong in the automotive and
high-tech sectors, including such leaders as GE, Honda, JDS Uniphase,
Nokia, Siemens, and Covisint.

"Some of the world's most innovative companies have helped us
develop our vision as the leading provider of product collaboration
solutions for the value chain. Our ability to execute against that
vision is enabling us to work with companies worldwide to improve
their financial performance by changing the way they bring products to
market," said Mark O'Connell, president and chief executive officer of
MatrixOne.

Quadrant should not be deemed to be an endorsement of any company or

opinion and is an analytical representation of a marketplace at and
for a specific time period. It measures vendors against
Gartner-defined criteria for a marketplace. The positioning of vendors
within a Magic Quadrant is based on the complex interplay of many
factors. Gartner does not advise enterprises to select only those
firms in the Leaders segment. In some situations, firms in the
Visionary, Challenger, or Niche Player segments may be the right match
for an enterprise's requirements. Well-informed vendor selection
decisions should rely on more than a Magic Quadrant. Gartner research
is intended to be one of many information sources and the reader
should not rely solely on the Magic Quadrant for decision-making.
